Brad Davis, Boniek Garcia and the Dynamo face a Timbers team that might just be the preseason favorites to win this year's MLS Cup. Diego Valeri, Darlington Nagbe and Will Johnson would be among the best midfielders in Major League Soccer no matter where they play, and they're all on the same team.

Kickoff at the Kino Sports Complex in Tucson, Ariz., is set for 7:00 p.m. ET.
